The Galaxy Nexus is Google's flagship phone. Regardless of whether or not "most people" need more than a 4 year old GPU for their Angry Birds, I really think there should be no compromises made with regards to hardware. When you're paying almost $300 for a top-end phone, you should have the OPTION to run graphically intensive apps on it at smooth as current tech will allow.

Technically, it's a developer phone. It's not made to have the best of the best.
